Problems with compiling OpenLDAP

Hello everybody.
I just download the openldap-devel.
I modify the Make-common for my system (linux debian).
Actually I nearly copy my old Make-common of my UMich ldap.
When I do the make, I get an error when compiling the string_to_key.c
file.
The error is that the 'mit-copyright.h' file missing.
I don't have this file, where can I get it please ?
Thanks in advance.
